The war of words between N.Y. Gov. Andrew Cuomo and the International Joint Commission is continuing,  as residents along Lake Ontario deal with weeks of flooding.

In a letter to Cuomo, the IJC says flooding was triggered by heavy spring rains. And it rejects his suggestion that preventive counter-measures -- like releasing more water through a downstream dam -- should have been made.

On the shores of the lower Niagara River, about 10 miles from Niagara Falls, a group of biologists from the U.S. Fish and Wildlife Service prepare to examine the largest fish species in the Great Lakes region – the lake sturgeon.


Governor Cuomo stopped in shoreline communities in Greece and Sodus Point to unveil some new technology designed to save homes and businesses from further damage from high water levels on Lake Ontario. 

Damage he says is due in part to a late response from the board that regulates water levels on Lake Ontario and the St. Lawrence River, the International Joint Commission.

Cuomo says the state is testing two "Aqua Dams," water filled synthetic device that, when it works, acts like a portable dam.

There will be more water flowing out of Lake Ontario in an effort to help ease the recent flooding conditions along the south shore.

The International Lake Ontario-St. Lawrence River Board agreed this week to increase the water flowing out of the lake at a greater rate. Secretary for the board, Arun Heer says this will be the highest outflow ever released from the lake on a sustained basis.

Because of that, Heer says officials will closely monitor the situation for a few days to see if there are any major adverse impacts.

The US Army Corps of Engineers predicts that water across the Great Lakes will remain high for the duration of summer, and even into the fall.

The Corps says these high levels are due to above average precipitation on the lakes. Forecasted levels on Superior, Michigan-Huron, and Erie will be the highest since the 1990s.

Lake Ontario levels will also remain high, after setting a record for highest average lake levels for the month of May. 

Communities along Lake Ontario -- ranging from Toronto to tiny Sodus Point, N.Y. -- have seen flooding for weeks.
